The test fails on this:
def g():
try:
return g()
except ValueError:
return -1
self.assertRaises(RuntimeError, g)
Changing that "return -1" to "return sys.exc_info()" shows that a
RuntimeError was raised indeed. Also, using TypeError or TabError
instead of ValueError gives the same result.
Shallow testing of the new methods seem to show normal results,
[Runtime,Value]Error.__[subclass,instance]check__([Runtime,Value]Error)
is False for cross-checks and True otherwise.
